ABSTRACT
Increasingly difficult geological-mining conditions make it necessary to seek new and effective ways of securing roadways. The new types of support must meet very high strength requirements and must own very high load-bearing capacities. These two conditions were taken into consideration when an SG type steel arch support was designed. The high strength of the arches resulted through using steel with improved mechanical parameters, while high load-bearing parameters were obtained through shaping elements of the support arches.
